In another embodiment not shown, the second charging connector 220 may be a fixed charging connector. The fixed charging connector means that the position and direction of the second charging connector 220 have been fixed, and the position and direction of the fixed charging connector will not change with external force. In order to achieve a good charging effect, it is therefore necessary to actively adjust and change the direction in which the mobile electronic device 100 enters the charging base 200 to adapt to the second charging connector 220 whose position and direction have been fixed.

The slide rail 230 is disposed in the accommodating groove 212, wherein the slide rail 230 has a first rail 232 disposed on the bottom wall 212a and a second rail 234 disposed on the side wall 212b.

The sliding cover assembly 240 is movably disposed on the sliding rail 230 for shielding or exposing the second charging connector 220 , and when the mobile electronic device 100 enters the charging base 200 and is accommodated in the accommodating slot 212 , the electronic device 100 moves when the mobile electronic device 100 is moved. Continued pushing makes the sliding cover assembly 240 move relative to the sliding rail 230 to expose the second charging connector 220 .

Specifically, the above-mentioned sliding cover assembly 240 includes a plate 242 , a pair of first sliding blocks 244 and a pair of second sliding blocks 246 . The plate member 242 is used for shielding the second charging connector 220, wherein the plate member 242 has a first end 242a and a second end 242b located on corresponding two sides. The first end 242 a of the plate member 242 is pivotally connected to the two first sliding blocks 244 , and each of the first sliding blocks 244 is correspondingly disposed on the first rail 232 to be slidable relative to the first rail 232 .

4 to 7 are schematic cross-sectional views of the mobile electronic device approaching and docking with the charging base for charging. Please refer to FIG. 2 and FIG. 4 at the same time, when the power of the mobile electronic device 100 is lower than a predetermined value, the mobile electronic device 100 moves toward the charging base 200 to be charged by the charging base 200 . Before the mobile electronic device 100 contacts the charging base 200 , the plate 242 covers the second charging connector 220 to protect the conductive terminal 226 of the second charging connector 220 from accumulating dust or being damaged by contact with foreign objects.

5 and 6 , the above-mentioned mobile electronic device 100 moves toward the first direction X to approach and contact the charging base 200 , wherein the front edge of the mobile electronic device 100 contacts and pushes the plate 242 .

It should be noted that the first end 242a of the plate member 242 is in a pivotal relationship with the first slider 244 , and the second end 242b of the plate member 242 is also in a pivotal relationship with the second slider 246 . Therefore, when the plate member 242 is moved toward the first direction X by the front edge of the mobile electronic device 100 , the first slider 244 is driven to slide toward the first direction X in the first track 232 at the same time. At the same time, because the material of the plate member 242 is hard (that is, it has no or low elastic deformation ability), the length of the plate member 242 is fixed, so the first end 242a of the plate member 242 is used as the rotation axis At the same time, the second slider 246 is lifted by the second end 242b of the plate 242 and moves toward the second direction Y .

Incidentally, along the first direction X, the cross section of the plate member 242 is substantially triangular, and the thickness of the plate member 242 increases from the first end 242a to the second end 242b thereof. Through such a shape arrangement, when the mobile electronic device 100 pushes the plate member 242, the second end 242b of the plate member 242 is lifted relative to the first end 242a. Alternatively, an inclined surface may also be provided in the accommodating groove 212 of the main body 210 to facilitate the movement of the plate member 242 and at the same time lift the second end 242b relative to the first end 242a.

In addition, the third end 260a of the rocker arm 260 is pivotally connected between the first end 242a and the second end 242b of the plate member 242, and the fourth end 260b of the rocker arm 260 is pivotally connected to the main body 210, so the plate member 242 While being pushed by the mobile electronic device 100 , the first slider 244 moves in the first rail 232 and the second slider 246 moves in the second rail 234 , and the plate 242 also drives the rocker arm 260 to move to the fourth end. 260b is rotated for the rotation axis, so that the third end 260a of the rocker arm 260 is raised relative to the fourth end 260b. By pivoting the third end 260a of the rocker arm 260 between the first end 242a and the second end 242b of the plate member 242, the rocker arm 260 can move the plate member 242 and the second end 242b can be lifted relative to the first end 242a. During the process, an auxiliary lifting effect is provided to make the movement and lifting process of the plate 242 smoother.

FIG. 8 is a schematic diagram of the sliding cover assembly 240 of the charging base 200 being pushed apart by the mobile electronic device 100 . Please refer to FIG. 7 and FIG. 8 at the same time, the first slider 244 slides to the bottom in the first rail 232 , and the plate 242 exposes the conductive terminal 226 of the second charging connector 220 , and enters the charging base 200 of the mobile electronic device 100 . The conductive terminal 112 of the first charging connector 110 contacts the conductive terminal 226 of the second charging connector 220 to form electrical conduction, so that the charging base 200 charges the mobile electronic device 100 .

Please continue to refer to FIG. 8 , in order to allow the mobile electronic device 100 to leave the charging base 200 , the plate 242 will automatically return to its original position to cover the second charging connector 220 , so it can be located at the fourth end 260 b of the rocker arm 260 A pair of torsion springs 270 are provided. When the mobile electronic device 100 enters the charging base 200 for charging, the moving plate 242 of the mobile electronic device 100 drives the rocker arm 260 to rotate, thereby causing the torsion spring 270 to store an elastic restoring force; and when the mobile electronic device 100 leaves the charging base After 200, the plate 242 is no longer subjected to the force exerted on it by the mobile electronic device 100, so the torsion spring 270 releases the elastic restoring force, so that the fourth end 260b of the rocker arm 260 is used as the rotation axis, and the third end 260a faces toward the axis of rotation. The reverse descending of the second direction Y drives the plate 242 to move in the reverse direction of the first direction X, so as to cover the second charging connector 220 .

To sum up, the charging base of the present invention is provided with a sliding cover assembly, so when the mobile electronic device is not in contact with the charging base, the sliding cover assembly can cover the second charging connector to reduce the connection between the second charging connector and oxygen and humidity. At the same time, it can avoid dust accumulation and prevent the conduction terminal of the second charging connector from being damaged by the collision of foreign objects.

In addition, through the setting of the sliding cover assembly, only when the mobile electronic device contacts and enters the charging base, will the sliding cover assembly be pushed open to expose the second charging connector, which is convenient for the first charging connector of the mobile electronic device to be connected to the second charging connector. The two charging connectors are docked for charging.

In addition, the second charging connector is presented as a pendulum-type charging connector, so that after the mobile electronic device enters the accommodating slot, the pendulum-type charging connector will swing relative to the body of the charging base when the mobile electronic device is pushed by the mobile electronic device, which is suitable for the mobile electronic device. The direction of the device entering the charging base allows the second charging connector to be docked with the first charging connector exactly.
